         6 . The cooling apparatus according to  claim 5 , wherein the carbon allotrope is graphite of which layers are separated through an exfoliation process. 
     
     
         7 . The cooling apparatus according to  claim 5 , wherein auxiliary cooling solution insertion grooves are formed on an upper surface of the cooling rod such that an auxiliary cooling solution and cotton are inserted into the auxiliary cooling solution insertion grooves. 
     
     
         8 . A cooling apparatus comprising a mat part with a circulation pipe installed therein so that water circulates through the circulation pipe, and a cold water circulation part, which is connected to the circulation pipe and cools circulating water, wherein the cold water circulation part includes:
 a case;   a cold water container, which is installed inside the case so as to receive water and connected to the circulation pipe;
 a cooling part for cooling the water received in the cold water container; and 
 a motor for circulating the water received in the cold water container, 
   wherein the cooling part includes:
 a cooling rod, which is formed in a rod shape and installed inside the cold water container; and 
 a cooling means for cooling the cooling rod, 
   wherein the cooling rod is formed in a column shape with a space formed therein, and includes a plurality of ice buckets in which ice is generated during cooling.   
     
     
         9 . The cooling apparatus according to  claim 8 , wherein the cold water circulation part is formed in a rod shape and installed inside the cold water container, has an outer circumferential surface that comes into contact with the cooling rod, and further includes at least one or more cooling tubes filled with an auxiliary cooling solution therein. 
     
     
         10 . The cooling apparatus according to  claim 7  and-9, wherein the auxiliary cooling solution is prepared by mixing 70 to 80 wt% of acetic acid and 20 to 30 wt% of salt. 
     
     
         11 . A cooling apparatus installed in a storage receptacle so as to cool an object to be cooled stored inside the storage receptacle, and comprising:
 a cooling rod, which is installed inside the storage receptacle by passing through a bottom surface of the storage receptacle, and a lower end portion of which is positioned lower than the bottom surface of the storage receptacle;   a cooling means installed on a lower surface of the cooling rod;   a heat dissipation part installed on a lower surface of the cooling means and dissipating heat generated by the cooling means to the outside; and   an auxiliary cooling ring, which is formed in a ring shape with a cavity formed therein so that the cooling rod passes through the cavity inside the auxiliary cooling ring, and which is installed at a position adjacent to a lower end portion of the cooling rod during installation.
